Abstract

The invention relates to a cellprotective, neuroprotective and retinoprotective composition. In an embodiment of the invention, said composition comprises (i) Ramipril or Ramiprilate and (ii) folic acid. The composition of the invention can be used, in particular, for the prevention of loss of vision, or even for improving visual acuity and visual field in normal subjects, as well as for treating ophthalmologic pathologies, in particular: glaucoma, diabetic retinopathy, age related macular degeneration, hereditary dystrophy of the retina, uveitis, ammetropia (myopia, presbyopia). This combination of active principles could also be used in general conditions for treating general pathologies (cancer . . . ).

Description

FIELD AND BACKGROUND OF THE INVENTION

The invention relates to a composition and, in particular, to a cellprotective, neuroprotective and retinoprotective composition which is especially appropriate for maintaining or improving visual function (visual acuity and/or vision field). In an embodiment of the invention, said composition comprises (i) Ramipril or Ramiprilate and (ii) folic acid.
The invention also relates to the use of said composition for the prevention or the treatment of different types of disease(s) or disorder(s) and especially of cancers or of ophthalmologic disease(s) or disorders involving chorio-retinal and/or optic nerve, resulting in a progressive loss of vision (visual acuity and/or field of vision).
Such effects on vision are observed, in particular, in glaucoma, macular degeneration, inherited retinal diseases, myopia, presbyopia, uveitis and diabetic retinopathy.
In an embodiment of the invention, a combination of angiotensin converting enzyme inhibitor (for example, ramipril or ramiprilate) and folic acid (or folate) and optionally one or several compounds chosen among vitamin B12, vitamin B6, Vitamin C, H4B (tetrahydrobiopterin), L-arginine, w-3 fatty acids (omega 3 fatty acids), magnesium, potassium, glucose and/or amino-acids (for example, a leucine, and especially an acetyl-leucine), in appropriate amounts, form a novel approach in the prevention and management of various diseases or disorders and, in particular, of ophthalmologic conditions such as glaucoma, glaucoma neuropathy, age related macular degeneration, inherited retinal dystrophies, myopia, presbyopia, diabetic retinopathy, or other diseases described herein.
The invention especially aims to provide compositions or medicaments (or drugs) and a kit intended for the prevention and/or the treatment of ophthalmologic diseases or disorders, which can improve visual function, in particular, the field of vision and/or visual acuity in patients suffering from neuropathies such as glaucoma, but also other chorioretinal disorders or deterioration of the optic nerve that may involve a vascular factor. Examples of ophthalmologic diseases that can be mentioned are:
1—Glaucomatous neuropathy, including glaucoma itself;
2—Degenerative chorio retinopathy;
3—Age-related macular degeneration (ARMD);
4—Hereditary dystrophies of the retina (including pigmentosa retinopathy and stargardt's maculopathy);
5—Retinal vascular occlusion;
6—Myopia;
7—Presbyopia;
8—Uveitis;
9—Diabetic retinopathy;
10—Corneal disorders, for example, keratoconjunctivitis, dry eye syndrome, or Fuch's corneal dystrophy; and
11—Physiologic visual degradation.
The invention is based, in particular, on the fact that when used to treat patients, Ramipril associated with a second particular active principle, for example, folic acid, causes not only an interruption—which until now has never been observed in patients treated for ophthalmologic diseases and especially diseases of the types mentioned herein—but moreover at least a partial inversion of the process of degradation of visual function, with an improvement in visual acuity and/or field of vision (usually both in visual acuity and field of vision).
In addition, it was found that folic acid, as well as other particular compounds and especially vitamin c, w-3 fatty acids and H4B augment the activity of Ramipril. Hence, the combination of Ramipril (or ramiprilate) with one or several of these active principles as discloses herein is more efficient to prevent or to treat some ocular pathologies and presents a more cell protective, neuroprotective and retinoprotective effect than each of these drugs used alone.
The combinations of active principles disclosed herein are not limited to the applications mentioned herein. They can be employed successfully to prevent or stow down or even stop a “natural” decrease in visual acuity, field of vision or both at the same time. In particular, they can be used successfully to prevent and even reverse visual decline in an aging animal (especially an aging human or non human mammal) and especially physiologic visual decline.
Mean retinal sensitivity reduces linearly with age. This decline starts very early on, from 20 years of age, and accelerates after the age of 60.
Moreover, it was surprisingly found that the invention can be applied successfully for the treatment of other types of diseases including cancer.
Ramipril, which is marketed, in particular, as Tritace®, Triatec®, Delix® or Altace®, has the following formula:
Ramiprilate, which results from de-esterfication of ramipril, has the following formula:
Folic Acid (also known as vitamin B9, vitamin M or folacin) has the following formula:
Folate (the naturally occurring form of folic acid) has the following formula:

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE PRESENT INVENTION

Unless otherwise indicated, each embodiment disclosed herein is applicable independently of and/or in combination with any one or several of the other described embodiments.
The term “Vision” or “visual function” as used herein encompasses visual acuity (more especially near and/or far visual acuity) as well as contrast vision, color vision and field of vision (also called visual field herein).
The term “loss of vision” or “degradation of visual function” as used herein includes partial or total loss of vision, and especially a partial or total loss in visual acuity (near and/or far visual acuity) and/or contrast vision and/or color vision and/or field of vision. It can result from a “natural” visual decline (i.e., it appears in the absence of any apparent eye disease or disorder), for example, in an aging animal, and/or from one or several ophthalmic condition(s) (in particular, an eye disorder and/or an eye disease) as disclosed herein.
The terms “treating” and “treatment” mean that an ophthalmologic condition (in particular, an eye disorder and/or an eye disease) is improved (at least partially) and, in particular, that the visual acuity and/or the contrast vision and/or the color vision and/or the field of vision of the treated animal is improved, or that the process of degradation of visual function is stopped.
As used herein, the term “ophthalmologic conditions” (or eye conditions) encompasses ophthalmologic disorders and ophthalmologic diseases involving chorio-retinal and/or optic nerve, resulting in a progressive loss of vision.
The term “ophthalmologic disorders” (or eye disorders) as used herein encompasses changes in vision, in the appearance of the eye or having abnormal sensations in the eye.

- night vision decline, and especially hemeralopia.

The term “animal” as used herein includes mammalians, in particular, humans and non human mammalians, and birds.
The term “mammalian” or “mammal” as used herein encompasses any of various warm-blooded vertebrate animals of the class Mammalia, including humans and non human mammals, characterized by a covering of hair on the skin and, in the female, milk-producing mammary glands for nourishing the young.
By “topical administration” it is meant herein an administration which has a local effect. This term includes especially a sub-tenonian administration, or an administration to the eye (especially on infra- or extra-ocular administration).
The administration to the eye can be performed, for example, by applying active principle(s) as disclosed herein (which can be, for example, in the form of an ophthalmologic solution, an ointment or eye drops) to the outside surface of the eye, i.e., by contacting the eye and especially the cornea with said active principle(s).
Alternatively or cumulatively, the administration to the eye can be performed by injecting active principle(s) into the eye and especially into the vitreous (i.e., via intravitreal injection), for example, in the form of an opthalmologic solution.
Active principles can be administered to the eye (for example, by application to the outside surface of the eye and/or by intraocular injection) using a delivery device which provides a controlled release of active principle(s) on the surface of the eye or into the eye. Said device can be, for example, placed in the lower cul de sac or conjunctival cul-de-sac, below the cornea, or injected into the eye, especially into the vitreous.
By “logical form”, it is meant herein a form appropriate for topical administration, and especially a solution (in particular, an ophthalmologic solution), a lotion, drops (in particular, eye drops), a cream or an ointment.
As used herein, the term “pharmaceutically acceptable vehicle” encompasses an ophthalmologically acceptable vehicle (or carrier).
The term “ophthalmologically acceptable vehicle” as used herein means any vehicle that has substantially no long term or permanent detrimental effect on the eye to which it is administered, in particular, any vehicle that can be placed in the eye and that does not cause eye irritation. Opthamologically acceptable vehicles include water (distilled or deionized water), saline solutions, phosphate buffered saline solutions, physiological serum, and other aqueous media.
By “consisting essentially of”, it is meant herein that minor ingredients can be added without having a major effect on active principles used in a composition, a medicament, a kit or a method as disclosed herein.
By “several”, it is meant herein at least two, i.e., two or more than two (for example, three, four, five, six, seven, eight, nine or ten or more than ten).
The term “adrenergic agent” as used herein encompasses an alpha adrenergic agonist agent, a derivative of an alpha adrenergic agonist agent, a beta-blocking agent, a derivative of a beta-blocking agents and mixtures thereof.
As used herein, an “alpha adrenergic agonist agent” is a drug which has effects similar to, or the same as, epinephrine (adrenaline) or which is susceptible to epinephrine, or similar substances, such as biological receptors. This term includes alpha 1 agonists, and alpha 2 agonists. Alpha 1 agonists stimulate phospholipase C activity in a human and an animal body, which results in vasoconstriction and mydriasis (excessive dilation of the pupil). Alpha 2 agonists are able to inhibit adenyl cyclase activity in a human and an animal body and are used notably as antihypertensives, sedatives, to reduce eye's aqueous humor secretions and to facilitate aqueous humor outflow via the uveoscleral route. Examples of alpha 1 agonist include neosynephrine. Examples of alpha 2 agonists include brimonidine, aprachlonidine and clonidine. Others alpha adrenergic agonist agents that can be used in the present methods and compounds of the present invention include methoxamine, methylnorepinephrine, oxymetazoline, phenylephrine, neosynephrine pivalat, beta-methylepinephrine, guanfacine, guanabenz, guanoxabenz, guanethidine, tizanidine, and mixtures thereof.
By “derivative of an alpha adrenergic agonist agent”, it is meant a compound obtained via a chemical modification of an alpha 1 agonist or an alpha 2 agonist, and which retains respectively the ability to stimulate phospholipase C activity or the ability to inhibit adenyl cyclase activity in an animal model such as a mouse, a rat or a monkey. Said derivatives are preferably amine-containing compounds, which more preferably have pKa's of greater than 7, preferably about 7.5 to 9. The alpha 1 or alpha 2 activity of a derivative of an adrenergic agonist agent can be shown, for example, by applying to one eye of a mouse, a rat or a monkey, few drops (one, two or three) of said derivative in solution in an ophthalmologically acceptable carrier, and applying, to the other eye of the same animal, the same volume of the ophthalmologically acceptable carrier alone, and comparing dilation of the pupil (in the case of an alpha 1 agonist derivative) or aqueous humor secretions (in the case of an alpha 2 agonist derivative) of both eyes. “Derivatives of an alpha adrenergic agonist agent” include imidazoline derivatives such as oxymetazoline, xylometazoline, tetrahydrozoline and the like. Also those derivatives defined in U.S. Pat. Nos. 7,345,077 and 7,335,803 can also be used as derivatives in the methods, compositions and kits of the present invention.
By “beta-blocking agent” (or beta-adrenergic antagonist agent) it is meant herein a drug which blocks the action of epinephrine (adrenaline) and/or norepinephrine (noradrenaline) in a human and an animal body. These compounds are used notably to lower intraocular tension and/or to reduce eye's aqueous humor secretions. This term encompasses antagonists of the beta 1, beta 2 and beta 3adrenergic receptors. The beta-blocking agents that can be used in the methods, the compositions and the kits of the present invention include timolol, sotalol, propranolol, penbutolol, nadolol, metoprolol, labetalol, esmolol, carteolol, bisoprolol, betaxolol atenolol, acebutolol, levobunolol, metipranolol and mixtures thereof.
By “beta-blocking agent derivative”, it is meant a compound obtained via a chemical modification of a beta-blocking agent as defined above, and which retains the ability to lower intraocular tension and/or to reduce eye's aqueous humor secretions in an animal model such as a mouse, a rat or a monkey. These properties can be shown, for example, by applying, to one eye of a mouse, a rat or a monkey, few drops (one, two or three) of said derivative in solution in an ophthalmologically acceptable carrier, and applying, to the other eye of the same animal, the same volume of the ophthalmologically acceptable carrier alone, and measuring and comparing intraocular tension and/or aqueous humor secretions of both eyes. Beta-blocking agent derivatives include guaiacoxy propanolamine derivatives such as those described in U.S. Pat. No. 5,804,603.
In a first aspect, the invention relates to a composition, in particular, to a pharmaceutical composition (or drug, or medicament), characterised in that it comprises, consists essentially of, or consists of several (i.e., two or more than two) active principles chosen among an angiotensin-converting enzyme inhibitor (also called ACE inhibitor or ACEI herein), folic acid, folate, magnesium, potassium, glucose, amino-acids (for example, a leucine, especially an acetyl-leucine), L-arginine, tetrahydrobiopterin (H4b), vitamin B6, vitamin B12, vitamin C, w-3 fatty acids, anti-inflammatory agents, beta-blocking agents, adrenaline, noradrenaline, alpha adrenergic agonist agents, anti-vascular endothelial growth factor (anti-VEGF) agents, a pharmaceutically acceptable salt thereof or a derivative thereof, and mixtures thereof.

In another aspect, the invention concerns the use of the active principles described herein for the manufacture of a composition, a medicament or a kit (as disclosed hereinafter) intended for use in inducing an improvement in visual acuity and field of vision in a treated animal (especially a human or non human mammal).
The invention also relates to a composition or a kit as disclosed herein, for the manufacture of medicament and, in particular, a cellprotector, a neuroprotector and/or a retinoprotector medicament, said medicament being intended for use in the prevention or the treatment of one or several disease(s) or disorder(s) as disclosed herein, and, for example, of one or several ophthalmologic conditions as disclosed herein, in an animal (especially a human or non human mammal).
In an embodiment of the invention, the manufactured composition or medicament is in the form of a tablet, a solution (for example, an ophthalmic solution), an ointment, a lotion, drops (for example, eye drops), an ointment or a cream. The composition or medicament and the kit of the invention are appropriate for caring out a method as disclosed herein.
In another aspect, the invention also relates to a kit which comprises or consists of:

- several (at least two) active principles chosen among an ACEI, folic acid, folate, magnesium, potassium, glucose, amino-acids (especially a leucine and, in particular, an acetyl-leucine), L-arginine, H4b, vitamin B6, vitamin B12, vitamin C, w-3 fatty acids, anti-inflammatory agents, beta-blocking agents, adrenaline, noradrenaline, alpha adrenergic agonist agents, anti-vascular endothelial growth factor (anti-VEGF) agents, their pharmaceutically acceptable salts or a derivative thereof and mixtures thereof; and
- optionally, instructions for using said kit,
  wherein said active principles are associated in the same composition or wherein at least two of these active principles are in separate compositions.

In an embodiment of the invention, the kit comprises or consists of:

- (i) a first active principle; and
- (ii) a second active principle; and
- (iii) optionally, a third active principle; and
- (iv) optionally, instructions for using said kit (for example, in a method of the invention),
  wherein the first active principle, the second active principle and—if present—the third active principle are as disclosed herein for composition 1, 2 or 3 and are associated in the same composition or wherein at least two of these active principles are in separate compositions.

The term “associated in the same composition” (or “present in the same composition”) means that the active principles present in the kit and, in particular, the first active principle, the second active principle and—if present—the third active principle as disclosed herein for composition 1, 2 or 3 are in the form of one single composition, i.e., that the kit comprises a composition of the invention (for example, composition 1, 2 or 3).
Alternatively, when “at least two of these active principles are in separate compositions”, this means that the kit of the invention comprises at least two or three separate compositions, each of these compositions comprising, consisting essentially of, or consisting of one or several active principle(s) (and a pharmaceutically acceptable vehicle, especially an ophthalmologically acceptable vehicle). For example, a kit which comprises a first active principle, a second active principle and optionally a third active principle as disclosed herein for composition 1, 2 or 3:

- may comprise only two separate compositions when:
  - (i) the third active principle is not present (in this case, one composition comprises the first active principle and the other composition comprises the second active principle); or
  - (ii) the third active principle is present but either the first, the second or the third active principle is separated from the two other active principles in a separate composition; and
- may comprises three separate compositions when the third active principle is present and when each of the three active principles is present in a separate composition (i.e., each of these three compositions comprises, consists essentially of, or consists of one of the three active principles, and a pharmaceutically acceptable vehicle, especially an ophthalmologically acceptable vehicle).

Or course, when the first active principle, the second active principle or the third active principle which is used in the kit or the methods of the invention comprises a mixture of several active principles, these active principles can be present in the same composition or alternatively at least two of these active principles can be in separate compositions.
The at least two or three separate compositions which can be present in the kit of the invention can be administered either simultaneously or not (in any order) to an animal (especially an aging human or non human mammal), for example, to carry out a method of the invention.
In an embodiment of the invention, the active principles present in the kit and, in particular, the first, the second and—if present—the third active principle present in the kit of the invention are associated with pharmaceutically acceptable vehicles allowing their administration, in different forms, in particular: enteral forms especially oral forms, parenteral forms, for example, intravenous forms or intramuscular forms, transdermal forms, and topical forms, in particular, topical forms appropriate for administration to the eye, including the topical forms appropriate for application to the outside surface of the eye, for intraocular or intravitreal injection and/or for sub-tenonian administration (for example, eye or ophthalmic solutions or eye drops). Clearly, the dosage of each of the active principles present in a composition, a medicament or a kit according to the invention can vary from one patient to another and fine tuning can be left to the clinician. When a composition, a medicament or a kit according to the invention are intended for treating of preventing a loss of vision and especially for treating of preventing eye conditions as disclosed herein, there is clear preference for topic forms of administration, in particular, eye or ophthalmic solutions or eye drops, in other words, in the preferred administration forms of a composition or medicament according to the invention or of the active principles present in the kit of the invention, the combined active principles used are associated with pharmaceutical vehicles that allow their clinical application in the form of eye lotions, eye ointment, eye solutions, or eye drops, preferably eye solutions or eye drops.
In an embodiment of the invention, at least two of the active principles of the kit are in separate compositions, and at least one of these separate compositions is formulated in a topical form appropriate for administration to the eye, for example, a form appropriate for contacting the eye with active principles as disclosed herein (especially eye drops or an eye solution) and/or for intraocular or intravitreal injection and/or is used for administration to the eye (for example, by contacting the eye with active principles as disclosed herein or via intraocular or intravitreal injection). In this case, the other separate composition(s) can be formulated either in a topical form appropriate for administration to the eye (for example, eye drops or an eye solution) or in another administration form, for example, in an oral form.
When the composition, a medicament or a kit according to the invention are intended for and/or is used for treating other types of diseases, and especially a cancer, any form of administration can be used, for example, any form appropriate for oral or parenteral administration.
In a further aspect, the invention relates to a method of preventing and/or treating one or several disease(s) or disorder(s) (in particular, one or several eye condition(s) as disclosed herein) in an animal (especially a human or non human mammal) in need thereof, said method comprising (or consisting in) administering to said animal at least two active principles as defined herein and, in particular, a first active principle, a second active principle and optionally a third active principle as defined herein for composition 1, 2 or 3 (or compositions) or medicament(s) comprising them), wherein said active principles are administered separately (i.e., in separate compositions) or not separately (for example, in the same composition), and wherein said disease(s) or disorder(s) is(are), for example, as defined herein.
In another aspect, the invention relates to a method for maintaining or improving vision and, in particular, the visual acuity and/or the field of vision in an animal (especially a human or non human mammal) in need thereof, said method comprising (or consisting in) administering to said animal at least two active principles as defined herein and, in particular, a first active principle, a second active principle and optionally a third active principle as disclosed herein for composition 1, 2 or 3 (or composition(s) or medicament(s) comprising them), wherein said active principles are administered separately (i.e., in separate compositions) or not separately.
By “administered separately or not”, if is meant herein administered in the form of separate compositions or not. Hence, when they are administered “separately”, this means that at least two or three separate compositions are used: in particular, when a first active principle, a second active principle and optionally a third active principle as disclosed herein are administered, at least two separate compositions are used when there is no third active principle and at least three separate compositions are used when a third active principle is used. By “not administered separately”, if is meant herein that at least two of these active principles are in separate compositions (as disclosed herein for the kit of the invention). These separate compositions can be administered simultaneously or not to the animal.
The methods of the invention can be performed using the kit of the invention.
Cumulatively or alternatively, the methods of the invention can comprise or consist in administering to an animal (especially a human or non human mammal) in need thereof a composition of the invention (for example, composition 1, 2 or 3).
In an embodiment of the invention, the composition(s) comprising active principles (for example, the first active principle and/or the second active principle and/or the third active principle as disclosed herein for composition 1, 2 or 3) which is(are) administered according to a method of the invention is(are) cellprotector, neuroprotector and/or retinoprotector composition(s).
In an embodiment of the invention, by “administering” it is meant herein applying active principles (for example, the first, the second and/or the third active principle as disclosed herein) and, in particular, the composition of the invention to the outside surface of one eye or both eyes of an animal (especially a human or non human mammal), and, in particular, contacting the surface of one eye or of both eyes of an animal with said active principles or with a composition of the invention. The administered active principles or composition can be, for example, in the form of an ophtalmologic solution, eyedrops or an ointment.
Alternatively or cumulatively, in an embodiment of the invention, by “administering” it is meant herein injecting in one eye or both eyes, especially injecting into the vitreous of one eye or of both eyes of an animal (especially a human or non human mammal), active principle(s) (in particular, the first, the second and/or the third active principle as disclosed herein), which active principle(s) can be, for example, in the form of an ophtalmologic solution.
The active principles and, in particular, the first active principle and/or the second active principle and/or the third active principle (or composition(s) comprising them) can be administered by the same route (for example, the topical route as disclosed herein) or via different routes, which routes can be chosen independently, for example, from the administration routes disclosed herein.
At least one of these active principles can be in the form of an ophthalmic solution or eye drops or ointment.
In one aspect of the methods of the invention (especially the method for maintaining or improving vision according to the invention), the treated animal (especially a human or non human mammal) has one or several ophthalmologic condition(s) as defined herein and/or is aged.
In an embodiment of the invention, a composition, a medicament, a kit or a method according to the invention is intended for or applied to a human being (or patient). In this embodiment, by “aged” or “aging” it is meant, for example, above the age of 50, above the age of 60 or above the age of 70.
Effective amounts and/or pharmaceutically acceptable amounts (especially physiologically or ophtalmologically acceptable amounts) of active principles, and especially of the first active principle, the second active principle and—if any—the third active principle are used.
As a way of illustration, an active principle is usually administered to a human or an animal in order to prevent or treat an eye condition in a concentration ranging from 0.001 to 15% (w/v), preferably from 0.05 to 10% (w/v), and more preferably from 0.1 to 3% (w/v). In particular, an active principle in the form of eye drops can be used, for example, in a concentration ranging from 0.1 to 5 % and more preferably from 0.5 to 3%, for example, in a concentration of 0.5%, 1% or 2%.
Especially Ramipril or Ramiprilate can be administered to a human:

- topically (for example, in the form of eye drops) in a concentration of 0.5 to 5% or 0.5 to 3%, for example, in a concentration of 0.5%, 1% or 2%; and/or
- orally in an amount of 0.5 to 5 mg/day, preferably 1 to 2 mg/day, for example, 1.25 mg/day; and

Folic acid or folate can be administered to a human,

- topically (for example, in the form of eye drops) in a concentration of 0.5 to 5% or 0.5 to 3%, for example, in a concentration of 0.5%, 1% or 2%; and/or
- orally, in an amount of 2 to 8 mg/day, preferably 4 to 8 mg/day, for example, 5 mg/day.

The compositions or medicaments that contain the active principles as defined herein may be administered to a mammalian eye as often as necessary to obtain an improvement of the disorder or disease (and especially of the ophthalmic condition). Those skilled in the art will recognize that the frequency of administration and duration of treatment depends on the precise nature of the active principles and its concentration in the composition, and various factors such as the type and severity of the disorder or disease, the age and weight of the animal, the animal's general physical condition and the cause of the disorder or disease. Within these guidelines, it is contemplated that the ophthalmic composition (preferably ophthalmic solutions or eye drops) of the present invention will be administered topically to the mammalian eye and, in particular, dropped into the eye and/or injected into the mammalian eye approximately once, twice or three times daily.
The duration of treatment administered in accordance with the present invention may range, for example, from a few weeks (at least one week) to a few months (at least one month), in particular, from 1 week to 8 months, preferably at least 2 weeks and less than 4 months and more preferably at least 3 weeks and less than 3 months. However, a prolonged treatment may be required. In particular, the treatment may last for one or several years or even for life, for example, in case of recurrence of the disorder(s) or disease(s) and especially of an ophthalmic condition.
Of course, one of several additional active principle(s), and especially one of several additional compounds for treating eye disorders and/or diseases may be used in the methods of the invention or may be present in a composition, a medicament or a kit according to the invention, provided that they do not interact with the first and second active principles and—if present—with the third active principle, to provide adverse side effects.

EXAMPLES

CLINICAL OBSERVATIONS

In the case of the clinical cases disclosed below, the active principles, in particular, Ramipril and folic acid ware administered continuously (i.e., at least once a day), in an oral form of 1.26 mg per day for Ramipril and 5 mg per day for folic acid or in a topical form.
The clinical observations disclosed below are, of course provided solely by way of illustration and do not in any way limit the scope of the invention. It is notable that equivalent observations were made in “normal” patients, which do not present any ocular pathology (in particular, aging patients above the age of 60), to whom the medicament was administered; these patients noticed an improvement of their vision, in particular, aging individuals regained the mean sensitivity that they experienced when they were much younger.
GLAUCOMA AMD GLAUCOMATOUS NEUROPATHY: the administration of the combination of Ramipril and folic acid in oral or topic form induces improvement in the visual function (visual acuity or visual field) and decreased intraocular pressure in 18 individuals.
MYOPIA: 3 patients were tested, The patient's vision was tested before and after the first eye-drop formulation was administered. 2 hours later, the patient's unaided distance vision improved. Wearing distance-corrected glasses, the patient vision improved.
PRESBYOPIA: 5 patients were tested. The patient's near vision was tested before treatment. 2 hours after this treatment the patient's near vision increased.
AMMETROPIA: improvement of near and distance vision 2 hours after treatment.
HEREDITARY DYSTROPHY OF THE RETINA AND PIGMENTARY EPITHELIUM:
1-Retinitis pigmentosa: this disorder corresponds to a dystrophy in the cones and rods. It is characterized by the appearance of night blindness in infancy or adolescence, progressive contractions of the peripheral field of vision and results in a substantial loss in visual acuity or even blindness by adulthood. Four patients were treated orally or topically and their visual acuity improved.
2-Stargardt's disease:
Two patients were treated visual. Acuity improved from 2 to 4/10.
AGE RELATED MACULAR DEGENERATION (ARMD): 12 patients were tested. The majority of patients presenting an age-related macular degeneration with or without sub-retinal neovessels treated with the combination Ramipril and folic-acid experienced improved visual acuity.
DIABETIC RETINOPATHY: All 10 patients were treated with the combination Ramipril and folic acid improved their vision and ocular fundus appearance.
KERATOCONJUNCTIVITIS BY DRY EYE: 2 patients received this treatment and their conditions were improved.
The term “visual function” as used herein should be understood to refer more particularly but not in a limiting manner to visual acuity or the field of vision or, as is preferable, to both at once. The invention thus concerns, in an embodiment, a cellprotective, neuroprotective and retinoprotective ophthalmologic drug that can interrupt the process of degradation of visual function and even reverse its course.
The invention is not limited to the use of the Ramipril and folic acid combination for the treatment of the disorders mentioned above. Especially, the combination of Ramipril and folic acid can also be associated, for example, with one or several compounds chosen among vitamin B12, vitamin B6, Vitamin C, H4B, L-arginine, w-3 fatty acids, magnesium, potassium, glucose, and amino-acids (for example, leucine and especially acetyl-leucine).
CANCER: an eighty old woman presented with an adeno-carcinoma (cancer) in the tongue. She received the same treatment (i.e., ramipril and folic acid), which was administered by the oral route and after four months of daily treatment, the volume of the tumour was decreased by about 30%.
It appears that the beneficial effect achieved by the folic acid and Ramipril combination may be explained by the increase of nitric oxide (NO) bioavailability in a cell. This is only a hypothesis and must be further explored.
The Increase of NO bioavailability improves endothelial function, significantly reduces endothelial dysfunction, acts against oxidative stress, significantly reduces inflammation, has antithrombotic activity and inhibits blood clot formation.
Ramipril as an ACEI or Ramiprilat reduces degradation of bradykinin stimulating NO reduction. Long term bradykinin stimulation enhances the release of NO. causing vasodilatation. Ramipril (or Ramiprilat) drastically reduces superoxide production and oxidative stress. But NO formation is critically dependant on the availability of the cofactor H4B which stimulates the conversion of L-arginine to L-citrulline and NO by NOS (NO synthase). Folic acid or folate (vitamin B8) stimulates endogenous H4B regeneration, a cofactor necessary for eNO synthesis, inhibits intracellular superoxide generation, and thus enhances the half-life of NO.
Impaired endothelial NO (eNO) activity is an early marker for cardiovascular disease. Most risk factors for atherosclerosis are associated with impaired endothelium dependent vasodilatation due to reduced NO production. Folate not only reduces plasma homocysteine levels but also enhances eNO synthesis and shows anti-inflammatory actions. It stimulates endogenous H4B regeneration, a cofactor necessary for eNO synthesis, inhibits intracellular superoxide generation, and this cellprotective, neuroprotective and retinoprotective ophthalmologic drug that can interrupt the process of degradation of visual function and even reverse its course.
The invention is not limited to the use of the Ramipril and folic acid combination for the treatment of the disorders mentioned above. Especially, the combination of Ramipril and folic acid can also be associated, for example, with one or several compounds chosen among vitamin B12, vitamin B6, Vitamin C, H4B, L-arginine, w-3 fatty acids, magnesium, potassium, glucose, and amino-acids (for example, leucine and especially acetyl-leucine).

Ramipril (or Ramiprilat) drastically reduces superoxide production and oxidative stress. But NO formation is critically dependant on the availability of the cofactor H4B which stimulates the conversion of L-arginine to L-citrulline and NO by HOS (NO synthase). Folic acid or folate (vitamin B9) stimulates endogenous H4B regeneration, a cofactor necessary for eNO synthesis, inhibits intracellular superoxide generation, and thus enhances the half-life of NO.
Impaired endothelial NO (eNO) activity is an early marker for cardiovascular disease. Most risk factors for atherosclerosis are associated with impaired endothelium dependent vasodilatation due to reduced NO production. Folate not only reduces plasma homocysteine levels but also enhances eNO synthesis and shows anti-inflammatory actions. It stimulates endogenous H4B regeneration, a cofactor necessary for eNO synthesis, inhibits intracellular superoxide generation, and this enhances the half-life of NO. Vitamin C augments eNO synthesis by increasing intracellular H4B. The ability of folate to augment eNO generation is independent of its capacity to lower plasma homocystein levels.
In conclusion, it is proposed that folic acid, vitamin c, w-3 fatty acids, H4B, L arginine and magnesium, augment the activity of Ramipril and thus may act in synergy with Ramipril by enhancing NO production. This would explain why this association is more efficient to prevent or to treat some ocular pathologies and presents as a more cellprotective, neuro and retinoprotective than these drugs used alone.
Hence, the common mechanism by which Ramipril, folic acid, vitamin c, w-3fatty acids, H4B, L arginine and magnesium, bring about their beneficial actions in various vascular and ocular diseases is thought to be by enhancing eNO production.
In view of the clinical observations, the combination of Ramipril and folic acid and, optionally vitamin B6, vitamin B12, vitamin C, w-3 fatty acids, H4B, L-arginine, potassium, magnesium, glucose and/or and amino-acids (for example, leucine and especially acetyl-leucine) could be judicious for a novel approach in the prevention and management of various conditions such as eye conditions (as disclosed herein) arterial hypertension, hyperlipidemia, coronary heart disease, atherosclerosis, diabete, neurodegenerative conditions (multiple sclerosis, Alzheimer disease, Parkinson disease, etc . . . ), rheumatism, general inflammatory and immune conditions, infections (viral, bacterial and/or parasitic infections), especially HIV infections, and cancer.
